As first relayed by Jeff Wilson at the Fort Worth Star-Telegram, ace Yu Darvish has been placed on the 15-day disabled list with inflammation in his right elbow. Darvish had a surprisingly-terrible start last Saturday in Houston — surrendering six runs on nine hits and four walks in a loss to the Astros — and then experienced discomfort in his pitching elbow at the beginning of a bullpen session on Monday.

Darvish will undergo further testing on his right arm later this week. Robbie Ross will start in his place on Thursday and Alex Claudio has been called up from Triple-A Round Rock to provide bullpen depth.
